Fatigue Damage Calculation - SCF ~ SN Curve?

The product or component design is often required to perform the #fatigue calculation, especially the permanent items across different industry.

The critical parameter that influence fatigue life is the stress range due to any operating condition.
Is it a low cycle or high cycle fatigue?

In the Oil & Gas industry, ranging from #offshore structure to the #subsea pipeline, most of the items are designed to withstand some harsh working environment, operating temperature/pressure fluctuation, external dynamic excitation due to wave and currents, etc.

What about fatigue analysis for pipeline installation?
How do you use #SCF to estimate the fatigue damage while #pipeline at catenary?
